You should configure the storage timeout intervals per the recommended settings for Storage Replication Adapter (SRA) to perform optimally in highly scaled environments.

Storage Provider settings

You should set the following timeout values on VMware Live Site Recovery for scaled environment:

Advanced settings

Timeout values

StorageProvider.resignatureTimeout

Increase the value of the setting from 900 seconds to 12000 seconds.

storageProvider.hostRescanDelaySec

60

storageProvider.hostRescanRepeatCnt

20

storageProvider.hostRescanTimeoutSec

Set a high value (For example: 99999)

You should also enable the StorageProvider.autoResignatureMode option.

Refer to Change Storage Provider Settings for more information on modifying Storage Provider settings.

Storage settings

When you hit a timeout, increase the values of storage.commandTimeout and storage.maxConcurrentCommandCnt to a higher value.

Note The timeout interval specified is the maximum value. You do not need to wait for the maximum timeout to be reached. Most commands finish within the set maximum timeout interval.
